Extruded batts - Cordierite Mullite Extruded Hollow Batts


Cordierite-Mullite kiln furniture is composed of cordierite, mullite and glass phase. Due to the high temperature resistance of mullite and the low expansion of cordierite, Cordierite-Mullite kiln furniture formed good property of excellent thermal shock resistance. Cordierite-Mullite kiln furniture can be used at 1350℃, which makes it can fulfill the production demands of most ceramic industry. Extruded batts have holes running the length of the cross section and are manufactured using high pressure vacuum extrusion, before being cut and surface-ground to guarantee the highest standard of flatness and dimensional accuracy. They are used mainly in the sanitaryware and glass panel industries, but can be found in a number of applications including the biscuit and glost firing of tableware.
